Hello all,
what would be the best approach to solve the "transform and multiply"
behavior? That is, a message retrieved from an endpoint is transformed,
multiplied and sent down the route pipeline.
The closest I was able to come up myself is the following route config. It
probably also better explains the desired behavior.
<route>
<from uri="jms:emailOutbox"/>
<camel:loop copy="true">
<xpath
resultType="java.lang.Integer">count(/net.phonemesh.integration.EmailMessage/to/string)</xpath>-->
<setHeader
headerName="to"><xpath>/net.phonemesh.integration.EmailMessage/to/string[${CamelLoopIndex}]/text()</xpath></setHeader>
<setHeader
headerName="from"><camel:constant>[email protected]</camel:constant></setHeader>
<setHeader
headerName="subject"><xpath>/net.phonemesh.integration.EmailMessage/subject/text()</xpath></setHeader>
<setBody><xpath>/net.phonemesh.integration.EmailMessage/body/text()</xpath></setBody>
<camel:removeHeaders pattern="JMS*"/>
<camel:removeHeaders pattern="breadcrumbId"/>
<camel:throttle timePeriodMillis="1000">
<camel:constant>5</camel:constant>
<inOnly uri="smtps://mysmtpurl"/>
</camel:throttle>
</camel:loop>
</route>
The little problem with the above is that it doesn't work :-). First,
${CamelLoopIndex} is not resolved and second the throttling inside of the
loop doesn't seem to produce the expected behavior (instead of the expected
5 email per second, it gives only 1 email a second).
Any input is very welcome.
Hynek
